Wulftec是一个著名的拉伸包装制造商includi吗ng rotary arm, turntable, and orbital formats. Each of these machines relies on AC motors fromBaldorand SE Encore speed-reducers fromWinsmith. Based on inputs from aRockwellCompactLogix controller and Rockwell PowerFlex 525 inverters, the Baldor motors are responsible for actuation. In the Model WCRT-200 machine shown here, which is capable of wrapping up to 150 loads/hr, this includes such things as lifting the film carriage, or causing the rotary arm to move, or causing the discharge conveyor to discharge a freshly wrapped pallet load. But while the motors are the source of actuation, the Winsmith speed reducers—often referred to as gear boxes—play a crucial role. By reducing the speed at which the motors rotate, they increase available torque.
“It means that a small motor running at a high speed is able to drive something very heavy at a slow speed because of the gear box ratio,” says Guy Lopes, Director of Operations at Wulftec. “After reducing the motor’s speed, the gear box drives a pinion, and the pinion drives a gear connected to the arm we want to rotate or the film carriage we want to raise and lower.”
leopes表示，质量，性能和紧凑的形状因素是Winsmith减速器的特点，使其成为Wulftec的机器建造者和设计师的吸引力。但在列表中也很高，很容易安装。
“We are able, through collaboration with Winsmith, to mount these gear boxes in any orientation,” notes Lopes. “This is not always the case with other suppliers, who may dictate that the gear box can only be mounted vertically or horizontally, for example. This flexibility in orientation simplifies the task of integrating the Winsmith component into our machine design. But it’s also valuable to our customers because if they need to replace a gear box for some reason, it’s easy to do so without worrying about the peculiarities of mounting.”
根据Winsmith Marketing Manager Steve Dunlap，SE Encore系列齿轮箱是唯一的直角减速器，可作为标准提供Winguard环氧涂层系统。这种保护措施可防止生锈并超越ASTM B-1000小时盐雾测试。另外标准说明Dunlap，是使用Mobil Glygoyle 460润滑剂，从而将扭矩额定值提高到15％。最后，高达97％效率的齿轮提高了扭矩能力，并减少了更长的性能的操作温度。
